It is very important to note that neither law school from Utah was considered in this ranking. The reason is two-fold: First, it is a given that BYU’s law school would be considered the most Mormon friendly law school each year. Secondly, if we were to remove BYU from the ranking of most Mormon friendly law schools in the country, the University of Utah would then become the number one ranked most Mormon friendly law school in the country and we just couldn't let the University of Utah be rankied number one so we decided to remove both schools from the running.

My guess is that the prestige points aren't based on overall rankings like USNWR, but on the prestige of the school in the local area. GWU has to compete with Georgetown, but ASU is king in the Phoenix metro area (and, to some extent, in Arizona on the whole).
